You, a doctor, an apostle, write to me: 'We all know by experience that we can be chaste, living vigilantly, frequenting the sacraments and stamping out the first sparks of passion before the fire can spread. And it so happens that among the chaste are found the finest men in every way. And among the lustful predominate the timid, the selfish, the treacherous and the cruel — characters of little manliness.'
